Details: I have a 2001 Nissan Xterra SE
I want to install a house battery into the vehicle. The battery I have been considering is the Universal Battery UB12750. Because this is an AGM battery, and it will be located behind the driver's seat, I'm concerned about overcharging the battery on long trips.
According to the battery specifications, for cyclic use it has a control voltage of 14.6 - 14.8 V. According to the alternator specifications for the Xterra, it has a regulated voltage of 14.1 - 14.7 V. Does this mean that the battery won't overcharge while connected to the main charging system?
Followup question: If there is still a risk of overcharging, would something like this work to protect the battery for my setup? I'm planning on using an isolator either way, but if overcharge protection is an issue I might select this one.
